  • Does a screw press machine affect oil yield of N sativa seeds?
  • Abstract: The effects of physical parameters of a screw press machine on oil yield of N. sativa seeds were studied using a KOMET Screw Oil Expeller. Different nozzle size (6, 10, and 12 mm), extraction speed (21, 54, 65 and 98 rpm) and diameter of shaft screw (8 and 11 mm) were applied in this study.
  • Do different nozzle size and diameter of shaft screw affect oil yield?
  • Different nozzle size (6, 10, and 12 mm), extraction speed (21, 54, 65 and 98 rpm) and diameter of shaft screw (8 and 11 mm) were applied in this study. Different nozzle size, diameter of shaft screw and rotational speed do effects the percentage of oil yield.
  • Which machine is used for oil extraction?
  • As a result, domestic consumers depend mostly on local mills to extract the oil from their desired sources. For industrial oil extraction, screw oil expeller is the most widely used machine. Screw oil expeller is a mechanical device which can generate pressure from rotation of feed to expeller screw manually or automatically.
  • How does a oil extraction machine work?
  • A 20 hp, 3-phase electric motor was used for running the machine and the rpm of the screw was maintained 140 rpm. A screw rotates inside the barrel of the press which creates pressure for the extraction of oil.
  • Does shaft screw size affect oil yield?
  • Different nozzle size, diameter of shaft screw and rotational speed do effects the percentage of oil yield. By using shaft screw with diameter of 8 mm had resulted to the decrease of oil yield with the increase of nozzle size and rotational speed.
  • How to increase the life of screw press & efficient oil extraction?
  • It is found from observation that the failure of screw causes extra costs which is undesirable. In addition, excess stress, bending, displacement may cause major overhaul of the press. So to increase the life of screw press and efficient oil extraction it is necessary to find exact stress and bending of the screw blades.
